Calculation
Your result
- Material removal rate
- 27 cm³/min
- Radial engagement
- 50 %
- Engaged cutting time
- 10 min
The quote handoff carries your inputs and assumptions. Only an explicit base cost is suggested as a quote cost; prices, rates and measurements remain planning notes.
Choose the tool and check the setup
Understand the cutting profile, material reference and equipment limits before applying the result.
Method & assumptions
Removal rate in mm³/min = axial depth × radial width × feed in mm/min. Divide by 1,000 for cm³/min. Engaged cutting time = target volume ÷ removal rate.
- Models a rectangular, constant-engagement cut. Entry moves, corners, changing engagement and air cuts are excluded.
- This is a geometric volume estimate, not a spindle power or safe cutting-load calculation. Select cutting parameters from your tooling guidance.
